XSpegpwrlw

class sherpa.astro.xspec.XSpegpwrlw(name='pegpwrlw')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC pegpwrlw model: power law, pegged normalization.

The model is described at [1].

PhoIndex

The power law photon index.

eMin

The lower peg for the normalization, in keV.

eMax

The upper peg for the normalization, in keV.

norm

The flux, in units of 10^-12 erg/cm^2/s, over the range eMin to eMax. If eMin=eMax then it is the flux in micro-Jy at eMin.

Methods Documentation

apply(outer, *otherargs, **otherkwargs)

calc(pars, xlo, *args, **kwargs)

get_center()

guess(dep, *args, **kwargs)

Set an initial guess for the parameter values.

Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.

regrid(*arrays)

reset()

set_center(*args, **kwargs)

startup()

Called before a model may be evaluated multiple times.

teardown()
